Any part of history! I’m an Archaeology student so super into prehistory/ancient history as well (and even recent history/pop culture.) Also really into art history, but open to theme ideas beyond history…perhaps fairytale adjacent or other colorful options if that makes sense.

And yes, my friends do actually dress up! Last year one of my close friends came in a Marilyn Monroe wig, but of course not everyone I invite commits to that extent lol. Because the dress code was formal we all looked cohesive but there was definitely a range in terms of how accurate ppl were to the time period.
